Patented Jan. 15, 1963 3,073,320 MAKE-UP KITS Donald A. Seaver, WestCheshire, Conu., assignor to Scovill Manufacturing Company, Waterbury,Coum, a

corporation of Connecticut Filed Juiy 9, 1959, Ser. No. 826,089 4Claims. (61. 13279) This invention relates to make-up kits andespecially to a tubular kit having a container for fluid material at oneend with a closure cap carrying an applicator for such fluid materialwhich is removable from the container with the cap. The cap may alsocarry an accessory tool projecting in the opposite direction from thatof the applicator which may be surrounded by a removable cover so as toact as a handle in the use of the applicator. Also, when the accessorytool is used, the container acts as a handle for such tool.

One problem encountered with prior make-up kits of the above type isleakage of the volatile material in the container around the applicatorand cap. In such makeup kits, an adaptor is inserted into the end of thecontainer which serves to carry a rubber wiper ring surrounding theapplicator and also has screw threads for the attachment of the cap.

Another problem encountered with such kits is that when the containerand applicator are made of different metals which is desirable forreasons of appearance and cost; that is, when the container is made ofbrass and the applicator of aluminum, electrolytic action would developbetween the two metals with the volatile material in the containerserving as an electrolyte which after a time, would result in a leakycontainer. One of the objects, in addition to the seal normally providedbetween the wiper ring and the applicator, is to provide a secondeffective seal between the cap and the container so that any materialwhich may escape under pressure around the wiper ring will,nevertheless, be confined. A further object of the container is to avoidany possibility of such electrolytic action.

Still another object of the invention has to do with ease and low costof manufacturing, particularly of the assembly of applicator, accessorytool and cap which, for reasons understood in the art, will preferablybe made of moldable plastic material.

A more detailed object of the invention is to provide an improvement inthe adaptor and wiper ring assembly wherein a single cup-shaped piece ofpliable plastic serves as:

. (l) A retainer for the wiper ring;

(2), A fluid-tight seal between the adaptor and the open end of thecontainer; and,

(3) A separator of inert material preventing electrolytic corrosion aswhen the container is made of brass and the adaptor of aluminum.

Other objects and advantages will appear from the description of thepreferred embodiment of the invention when considered in connection withthe accompanying drawing, wherein:

PEG. 1 is a longitudinal vertical section through the make-up kitembodying my invention;

FIG. 2 is an exploded perspective view of the parts forming the adaptorand wiper ring assembly;

FIG. 3 is a similar view of the parts forming the cap and applicatorunit;

FIG. 4 is an enlarged view ofthe adaptor and wiper ring assembly showingit in the process of being inserted into the open end of the containershell; and

FIG. 5 is a similar view showing these parts completely assembled.

Referring now to the drawing, the numeral 30 desig:

nates generally a make-up kit consisting of a container shell 11, anadaptor and wiper ring assembly 12, a cap and ap! plicator unit 13having an accessory tool 14 (here shown as a comb) and a cover 15.

The cap and applicator unit 13 consists of a cap 16 carrying anapplicator in the form of a cylindrical rod 17 which extends into thecontainer shell 11 and wherein the inner end of said rod 17 is formedwith a series of circumferential ridges and grooves indicated at 18, bywhich the material in the container is picked up and removed therefrom.

The container shell 11, preferably made of brass, is formed with atapered rounded closed end 19 and an opposite open end 20. The materialstored within the container shell 11 is often a volatile substance, suchas mascara for eye make-up; therefore, it is important, when the cap andapplicator unit is threaded into closed position, to provide sealingmeans which will insure against leakage when the kit is not in use orstored and to pervent deterioration and hardening of the material withinthe container.

The adaptor and wiper ring assembly 12 consists of a bushing 21, a cup22 of pliable plastic material and an annular rubber wiper or O-ring 23.Specifically, the bushing 21 is made, preferably of aluminum, and isformed to provide a cylindrical plug end 24 projecting into thecontainer, a circumferential shoulder 25 and an exterior threaded end 26projecting outside the container, The bushing 21 is provided with acentral opening 27 through which the applicator rod 17 is adapted to beinserted or removed. The lower end of the plug end 24 is provided with acounterbore or annular recess 28 in 'which the O-ring 23 is located. Theplastic cup 22, in

its initial state before assembly, is best shown in FIGS. 2 and 4, ashaving an end wall 29 and a cylindrical wall 30. The end wall 29 isprovided with a central aperture 29a to accommodate the adaptor rod 17when passing therethrough. The outside diameter of the cup near the endwall 29 is somewhat smaller than the remainder of the cup for thepurpose of guiding same in the open end 20 of the container shell duringassembly. It is to be noted that the outside diameter of the bushingplug 24 is considerably less than the inside diameter of the containershell open end 26. l Also from FIG. 4, it will be noted that theover-all length of the cup wall 39 in its initial state is somewhat lessthan the over-all length of the plug end 24. The wall thickness of theplastic cup is somewhat greater than the annular space between thebushing and container wall. Therefore, it will be apparent that when theadaptor and wiper ring assembly 12 is forced into the open end 20 of thecontainer shell 11, the wall thickness of the cup will be reduced and atthe same time, the wall length will be extended thus filling the annularspace between the plug end 24 and the container open end 20. From theabove dimensional fits, it will be apparent that after assembly, the cupwall 30 will be under a constant compressive force, thus assuring anefiective seal between the open end 20 of the container and the bushingplug end 24.

Also, the wiper ring 23 is dimensioned to have a snug or binding fitaround the applicator rod '17; the use of a rubber Q-ring assuresthe-ring will conform to any irregularities which may occur in thesurfaces of the rod, thus normally effecting a seal at that point.

'It is to be noted from FIG. 5 that when the adaptor and wiper ring unit12 is force-fitted into the open end 20, it is driven to a positionwhere the upper surface of the bushing shoulder 25 is positioned anoticeable distance below the terminal edge of the shell open end 20thus leaving the edge of the shell exposed as indicated at 31 forreasons which will appear later.

Also in FIG. 5, it is to be noted that the outside diameter of thebushing shoulder is slightly less than the inside diameter of the openend 20 and by reason of the compressed cup wall 30, said shoulder willbe centralized relative to said open end so that no part of the bushingwill contact the container shell. This is desirable when the containershell and the bushing are made of different metals, such as brass andaluminum, in order to avoid any electrolytic action from developingwhich would set up a corrosive action between the assembled parts.

Considering now the constructural details of the cap and applicator unit13, the cap 16 is preferably made of a pliable plastic material, such aspolyethylene, and is formed with a larger cylindrical section 32 and asmaller cylindrical section 33. The larger section 32 is provided withan interior threaded recess 34 which engages with the bushing threadedextension 26 for removably joining the cap and applicator unit 13 to thecontainer shell 11. The smaller section 33 is provided with a socketwith in which is received a cylindrical connector portion 36 thatintegrally joins the accessory comb 14 to the applicator rod 17 togetherin alignment and on opposite sides thereof. A central passage connectsthe cap threaded recess 34 to the socket 35 for receiving the applicatorrod 17 therein. The cylindrical connector portion 36 is formed with acircumferential recess 37, and the socket 35 of the cap smaller section33 is formed with a complementary inwardly extending rib 38.

In assembling the applicator tool to the cap 16, the applicator rod 17will first be inserted through the cap central passage 40 and finallythe cylindrical connector portion 36 will be forced into the socket 35.Due to the fact that the cap 16 is made of pliable plastic material, itwill be understood that the wall of the smaller diameter section 33 isof sutficient resiliency to permit the leading end of the cylindricalconnector portion 36 to be forced past the rib 38 until the latteraligns with the connector recess 37 and there snaps in place to hold theapplicator tool and cap 16 together as a unit.

When the cap 16 is assembled to the bushing threaded extension 26, theexposed annular edge 31 of the shell 11 will abut against the adjacentsurface of the cap 16 which projects over the shell. Thus, the metaledge will seat itself into the pliable plastic material of the cap andassure against any possible leakage of material which might escape pastthe wiper ring 23 or around the plastic cup 22.

FIG. 1 shows a metal sleeve 39 surrounding the larger section 34 of thecap 16. While this sleeve may incidentally serve as a decorative piece,its primary purpose is to strengthen that portion of the cap 16surrounding the interior threaded socket 34 and prevent the threadedextension from stripping out in case abnormal tightening pressure isapplied to the cap 16 when assembling it to thecontainer shell 11.

While only one form of the invention is disclosed, it is to beunderstood that various modifications may be made in the inventionwithout departing from the spirit of the following claims.
